Project: Ironside Energy, LLC

Customer: Arcdor Mittal

Location: East Chicago, Indiana

Capacity: 50 MW electric / 460 kpph steam

Project Description:
Arcdor Mittal and Primary Energy partnered to develop additional on-site energy capacity, reduce energy costs and provide a more reliable, secure source of power and steam for Indiana Harbor Works and to address an opportunity to recover additional blast furnace gas. Primary Energy installed and owns a 50 MW combined heat and power (CHP) facility comprised of a blast furnace gas recovery boiler and a condensing steam turbine.

Commercial Operation: December 2002

Benefits:
The Ironside Energy CHP facility allows Arcdor Mittal to capture and beneficially use practically all of the byproduct gas that would otherwise be flared, thereby producing useful electricity and reducing net pollution into the environment.

The United States Environmental Protection Agency recognized Ironside Energy's 2007 operations for high environmental efficiency. The plant produced 270,000 fewer tons of carbon dioxide when compared to other plants using separate heat and power sources.
